Any trapper works, but I'd say artificers is an even better complement for these particular type of stages.
For the one with a ground tile in the middle of 4 tower with a bunch of enemies you can just place a device to capture them all, with it being completely invincible and depending on the artificer, it doesn't even run out.
They can influence as many positions, but they can't be triggered away and don't need you to clear the tile first.
